Yes. But there also is research on porn.
It is a long time that I have been to university, but I have similar trouble with customers. Our Engineers waste a lot of time trying to get software we developed for a customer to the customers engineers because any of the following occur frequently:
* dropbox is blocked
* .exe and .dll are not allowed in e-mail
* our hoster is in a class A net blacklisted by customers spam-filter
* we chose a file name that matches some regular expression deemed dangerous by their IT staff
* sftp is blocked
and so on, and so on
This is fine, if there is a clear procedure handling these exceptions. (e.g. if a researcher writing a paper on porn site can walk up to the IT appartment and get a list of sites opened for his computer within in minutes.) But ultimately these restrictions serve no real purpose and just waste a lot of money in the form of time lost by both IT, administrative and research staff.
Also, I wonder if research really works, if researches have to convince a censoring body that there request to access a site is legitimate before they can proceed with their research. (Yes sir, gamesexpert.com is not a sex site!)
